I'm getting gas only in my port side exhaust. The block has 0 hours on it. All of the injectors have been cleaned and serviced. I even changed the computer on that motor. Not sure what to do now. 'My mechanic is stumped also??

What engine is it 454 - 502 mag with vst ? the title and content of the thread are two different things, does it run

Yes 502 with a vst

And getting gas in the oil

and you know this how ??...I'll ask again, does the engine run

Think vst overflow dumps into a intake port on that side if it was malfunctioning, at least it did on mine....

Yes, it runs . On the hose, starboard side exhaust is clean fresh water, port side is full of fuel, its white and beads up on your hand and smells of gas. Also after running 5 min on the hose the oil smells like gas

Im not well versed in VST, camp 69 may be onto something, excessive amount of fuel ( flooding ) could wash down the cylinders push it passed the rings and into the pan

Mechanical fuel pump? Another possibility

Not sure if to much fuel would make the oil white, think water would do that, check the vst, there is a small black hoes that goes directly to a fitting on the intake that dumps excess fuel.
